A teardown of the upcoming update to Gmailfor Android -- Gmail 4.6 -- revealed numerous confirmations that ads lay lurking in the update from Google Inc. (GOOG), as well as showcasing some welcome improvements.

Notably Android Policefound strings, 8 classes, and even a full library with "Ad" in their names in the Gmail APK. A big question left unanswered by the teardown is whether the feature will harass users with fake email ads, a feature added in a recent controversial update to the desktop browser client, or simply ad normal banner ads like those found in many free (ad-supported) Android games.

The Droid Guyis claiming the changelog for Gmail 4.6 hints that the new mobile ads will be in the form of email spam.

The update does bring some welcome changes in a heavy overhaul to the Gmail card, including a warning about unset messages, new icons for contacts you don't have a picture of (a stylish letter from their first initial), and darker UI icons.

The reviewers were indifferent or perhaps slightly negative on the decision to do away with the "cancel" button in the email "send" dialogue, which now requires you to press the "back" button (beneath the screen) to cancel.

Most Android users should get the tile "upgrade" sometime later this week, bringing their freeloading mobile Gmail days to an end.

By bias do you mean 2 different sources finding it in the code or bias in that someone would be foolish to think they would implement the same ad technology into their mobile platform they did to their browser platform.

I ser your point, they really are stretching thongs a bit.

All sarcasm aside. Google makes their money off ads. To assume otherwise is foolishness. It's not to say there is anything wrong with Android,it's a very capable mobile os. Just don't kid yourself. Like Facebook Google needs to make money also and this is their core business, collecting info and selling it first and foremost.
